Preserving Christchurch's unique heritage – Firth, supplied concrete, shotcrete and varying mixes for the Isaac Theatre Royal

Concrete for Christchurch post-earthquake theatre restoration supplied by Firth


Just like a theatre performance, what goes on behind the scenes during a restoration project is fundamental to its success.

For the Isaac Theatre Royal project, it started with new foundations. All the concrete for the piling was supplied by Firth, for customer McMillan Drilling, but that was just the start. Firth also supplied shotcrete for South Island Shotcrete Ltd to spray onto the interior of the building, and varying custom concrete mixes for main contractor, Naylor Love Construction.

Firth says the company needed to ensure the mixes would complement and strengthen the existing parts of the structure. Other challenges included working around the steel formwork, in tight situations with limited access.

Firth has played a major role in helping to rebuild Christchurch following the 2011 earthquake, to the extent that the company has invested in a third, and now fourth plant in the city.

Dominic Sutton, head of operations and sales Certified (Southern), says Firth is very happy to be playing such a big part in the preservation of some of the city's grand old structures.


"As a Cantabrian, watching the Isaac Theatre Royal come back to life, and knowing Firth was part of that, has been very satisfying."

Firth's roots go back to 1925, when the company began operations in Rangiriri. It has had a base in Christchurch since 1956, and has become one of this country's best known, trusted and most enduring brands. Today Firth's product range includes Certified Concrete®, designer brick, paving, architectural masonry and retaining walls.
